[0005] The diameter of the small ring is smaller than that of the central non-data area, and vertically placed to the inner side of the container bottom; the vertical height of the small ring is as same as that of the larger arc shoulder designed on the big sector area on the upside of the container bottom.

[0006] On the core of the support base, the top is a ring-type core neck composed of a pair of rigid disk protection slip and elastic locking slip; the diameter of the protection slip is a bit bigger than that of the locking slip; the height of the disk protection slip is a bit higher than that of the locking slip and the button.

[0007] The vertical height of the small ring is as same as that of the inner ring of larger outer gear-shaped circle and the arc shoulder on the outer ring, thus form the disk supporting assembly.

[0008] The three radial lines from the sector centre in the container bottom is connected in segments with the small ring, hence forming the central rigid supporting assembly, the height of the extending enforced tendon is a bit lower than that of the small ring.

[0009] The protruding paper-holding spring with long arc existed on the center of the container back The length of the protruding arc is a bit shorter than that of the container back.

[0010] The bottom side of the container exists a large ring supporting base.

[0011] Compared with the prior art, this invention offers a elastic bridge structure with rigid and flexible interaction composed by the button, small elastic sector and the locking slip. And this container is also designed with a small circular support ring, hence, avoiding the problems such as the smaller support area in the central support base and the imbalance of the support force borne by the disk.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0031] As shown in the figures, the container back 13 is respectively connected with the container bottom 12 and the container cover 11; a book-like container is formed by folding the container bottom 12, the container back 13 and the container cover 11 together; a disk support base 18 is designed in the inner side of the container bottom 12; said support base 18 includes button 21, a pair of small elastic sector area 15 and locking slip 20, which form a straight elastic bridge together with connection piece 15D and the concave slot 28; The button 21 is a cylindrical button with a flat top; said a pair of small sector area 15 is in symmetry of the core of the disk support base; the two ends of the elastic bridge are connected with the cone-shaped pier 15A and extended to be connected with the base of the small ring 26; the small elastic sector area 15 is designed with a locking slip 20 which is equipped with a locking wing 20A.

[0032] The disk support base 18 also includes a rigid support large sector area 16, which is respectively connected with the inner side of the container bottom 12 in segments by the rigid tilting surface 16C and small ring 26. The small ring 26 is vertical to and connected with the container bottom. The rigid support large sector area 16 is designed with an arc support shoulder 17 and disk protection slip 19. On the top of the core of the support base 18, a ring neck is formed by a pair of rigid disk protection slip 19 and a pair of elastic locking slip 20 in segments. The diameter of the protection slip 19 is a bit bigger than that of the locking slip 20, but a bit smaller than the diameter of the central hole of the disk. A segment circle is formed by the rigid disk protection slip 19 and the locking slip 20. The protection slip 19 is vertical to and connected with the larger sector area 16. And the height of the disk protection slip 19 is a bit higher than that of the locking slip 20 in its static status. The small ring 26 has the same core with arc shoulder 17 over the rigid support large sector area 16. Besides, the small ring 26 has the same height with the arc shoulder 17 and the protrudent support shoulder 12D of the bottom 12.

[0033] The support base 18 also includes three radial strengthening tendons designed in the back of the container bottom 12. With the core of the large sector area 16 as the radial point, the tendon extends along the base of the sector area and the central line of the sector area to form three radial lines 16A, 16B, these three radial lines 16A, 16B extend to the rigid tilting surface 16C in the inner side of the container bottom and form enforced keels 27, which are respectively connected with the rigid tilting surface 16C and the small ring 26. The enforced keels 27 have the same height with the radial lines 16A, 16B.

[0034] The center of the container back 13 is designed with an extended and protrudent arc baffle 13A, which enhances the rigidity of the container back and prevents the container from being deformed.

[0035] The container is designed with a cylindrical button 21 with a flat top. And a straight elastic bridge is formed by the button 21, a pair of small sector area 15 with the core of the support base 18 as the symmetrical point and the concave slot 28. The two ends of the elastic bridge are connected with the cone-shaped pier 15A. When adding pressing force, the bridge will elastically sink to become a concave arc, the concave slot 28 and the cone-shaped pier 15A will incline towards the center. When the pressing force is released, the bridge will quickly return to its original position owning to its upward elasticity and the transverse eccentric force from the two ends of the cone-shaped pier applied to the bridge. At the same time, the concave slot 28, the locking wing 20A of the locking slip 20 and the button 21 will also quickly return to their original position.

[0036] The central button 21 and the arc locking slip 20 which is symmetric to the button 21 and with some extended space are located in the two ends of the bridge center. The cylindrical button 21 is located in the center of the bridge. When force is applied to the button 21, it will be transmitted to the concave slot 28 at the two ends of the bridge center and the small sector area 15 through the base of the button 21. The force applied to the two ends of the bridge will cause the bridge surface to elastically deform at the central point as the symmetrical position. Meanwhile, the concave slot 28 connected with the bridge surface, the locking slip 20 and the locking wing 20A in the top will also be turned inward, with even downward shift along the axial direction. When the diameter of the locking wing 20A is smaller than that of the central hole of the disk, the central hole of the disk shall upward deviate the core neck and locking wing along the axial direction, the lower edge of the center hole will be placed over the locking wing 20A. The location of concave slot 28 will make the central button 21 become easy, convenient and safe to be touched on by finger.

[0037] The small ring 26 has the same core with the center of the small sector area 15 and the large sector area 16, the outside diameter of the small ring 26 is a bit smaller than that of the non-date area near the central hole of the disk. The small ring 26, the protrudent support shoulder 12D of the large ring and the arc shoulder 17 on the rigid large sector area 16 have the same height, with the function of effectively supporting the non-data area of the disk. The disk will be kept at the same level without any distortion.

[0038] The outer diameter of a pair of the arc protection slip 19 is greater than that of the arc locking slip 20, but a bit smaller than that of the central hole of the disk. The disk protection slip 19 is a bit higher than the button 21 in its natural status, with the functions of placing the disk and protecting the button from being activated so as to securely holding the disk when the container is closed.

[0039] The small ring 26 and the enforced keels 27 not only enhance the strength of the whole support base 18, preventing it from being deformed, but also keep the front and back surfaces of non-data area on the disk from being affected its stable storing owing to the pressing force from axial and diameter direction. In addition, the whole structural assembly of the support base 18 shall permanently retain the designed position, avoid of deformation.

[0040] When container is used to hold the disk, the edge of the central hole of the disk 25 shall be put right toward the disk protection slip 19A, the two locking slips 20 and the above locking wing 20A. Under the navigation of the disk protection slip 19, the locking wing 20A shall hold the two symmetrical edges 25A of the central hole of the disk 25, making the disk stay in the temporary suspension status. When applying moderate force to lightly press the disk, the two locking wings 20A will receive downward axial pressing force from the edge of disk center hole. The force shall be transmitted to the locking slip 20, the concave slot 28 and the elastic bridge surface 15C which appears to be concave surf, when the diameter of two locking wings 20A is smaller than the diameter of 25A, the incline degree of the elastic bridge surface 15C will be close to the maximum value. In this case, the edge 25A of the central opening of the disk 25 shall move downward through the locking wing 20A due to the push of the finger. And the non-data area of the disk shall contact the rigid arc shoulder 17 on the large sector area 16, the small ring 26, arc shoulder 12C and the protrudent support shoulder 12D inside the large ring. Meanwhile, the elastic force from the pier 15A and the elastic bridge surface 15C will be released; the concave slot 28, the locking slip 20 and the locking wing 20A will quickly return to their original position; the locking slip 20 and the locking wing 20A will be meshed with the relevant position on the edge of 25A. The center non-data area and edge non-data area on the disk are evenly positioned on the symmetrical and rigid arc support shoulder 17, small ring 26, arc shoulder 12C and the outer arc-shaped protrudent support shoulder 12D. Due to the three enforced radial lines 16A and 16B of the large sector 16 extending to the inner side of the ring 26 to form enforced keels 27 along the rigid tilting surface 16C, the strength of the support base 18 is enhanced. In addition, the small ring 26, the arc shoulder 12C, the outer circular protruding support shoulder 12D respectively and properly support the non-data area of the disk 25 and the outer edge of the disk 25B, so the disk can be stably located on the support base 18. The button 21 and the locking slip 20 are a bit lower than the disk protection slip 19. The rigid disk protection slip 19 may resist the external force and prevent the button 21 from being improperly activated owing to the force. Then close the cover 11. Now the inner arc disk pressing slip 11 C and the extended arc spring 13A on the container back 13 will moved consequently, so as to be closed with the container bottom 12, also the edge of the under surface of the disk 25C is symmetrically limited inside the large ring. The spring 13A can not only firmly holding the disk and instruction of the disk, but also enhance the rigidity of the container back. Therefore, the container can bear more pressing force, in avoid of being damaged caused by pressing or over-weight during transportation or moving.

[0041] When taking out the disk, the user shall lightly press the button 21 which evenly transmits the force to the concave slot 28 and the elastic bridge 15C. With the equal downward axial force from reverse direction, the bridge 15C shall gradually sink to become the concave surface; the two locking slips 20 and the above locking wing 20A shall shrink toward the center in the radial direction and downward in the axial direction due to the light distortion force of the concave slot 28. Due to the the three radial lines 16A, 16B on the back of the two large sector area 16 respectively extending to the inner surface of the container bottom to form the enforced keels 27 and the small ring 26 in the inner surface of the container to form the rigid support base so as to resist the elastic pressing force, hence firmly holding the non-data area of the disk and preventing the supported disk from being deformed owing to the elastic force. When the diameter of the two locking wings 20A is forced to be less than that of the central hole 25A of the disk 25 by the pressing force from the button 21, the central hole 25A of the disk 25 shall not be affected by the friction force from the locking wing 20A, and the disk shall move upward. Then the gradient of the elastic bridge 15C shall be close to the maximum value. The arc shoulder 17 on the larger rigid sector area 16 is designed to share the same surface with small ring 26 in order to prevent the disk from moving downward. When the pressing force of the button 21 is released, the locking wing 20A shall firstly return to the initial outer position along the radial direction; the top of the locking wing 20A shall hold the edge of the lower surface of the central hole 25A of the disk 25. Under the force of the elastic bridge 15C, the whole disk shall quickly move upward with the navigation of the disk protection slip 19, and be ejected from the support base 18. Then the disk shall be easily taken out.

[0042] Compared with the prior art, the present invention has the following achievements and advantages:

[0043] 1. The small ring is designed to enhance the rigidity of the core base, so as to obtain the stable, safe and reliable effect.

[0044] 2. A concave slot is designed in the connection between the elastic bridge and the button, hence making the connection parts smaller and thinner, decreasing the pressing force of the button and increasing the elastic force for returning to the original position, making it easier and more convenient to take out the disk.

[0045] 3. The disk protection slip is a bit higher than the locking slip, thus effectively preventing the pressure on the core base from the outside of the container cover, preventing the central hole of the disk from deviating the support base, effectively protecting the disk from deviating the support base.

[0046] 4. The three radial enforced tendons on the rear of the container bottom extend to the inside of the container and connect with the small ring to form the core base with greater stability and rigidity, hence effectively prevent the disk from being deformed and damaged. Meanwhile, they shall restrict the two large sector areas on the core base from being tilted and deformed owing to the external force.
